New STDIN mode

[Alkarex]

New continous mode using STDIN to pass messages. Useful for larger / faster payloads.

Related to #20 (sorry for the poor coordination on my side)

Example of Python code:

import json
import sys

for line in sys.stdin:
    msg = json.loads(line)
    msg['payload'] = msg['payload'] * -1
    print(json.dumps(msg, separators=(',', ':')), flush=True)
